Scarlett Johannson, who just gave birth to her daughter three months ago, is W Magazine's March cover star. The new mom has been in the spotlight since she was seven years old, and she's opening up to W about her daughter, her career, and of course - her now-famous voice.

When asked about that deep voice and how it affected her childhood and then career, Scarlett said, "When I was young, I would talk and everyone thought I had a cold. But when I went out for films, they loved my voice. It was a different world."

We know what you're thinking as you look at these photos, "No way she just had her baby!" Well yes, she did -- she looks this incredible just three months after giving birth! She joked about her daughter, "When she came out of me I was so surprised. I had a very strong picture in my mind of what my baby would look like, and, of course, she is completely different. Perfect, but not what I'd imagined."

Johannson has played such a variety of roles -- from superheroes to computer operating systems -- something not many actors can say. "I had a big imagination. I particularly loved Judy Garland, and, to me, she did it all. For as long as I can remember, I wanted to be an actor. And I wanted to do everything."
